Intel Core 2 Performance Comparison Guide

The Intel Core 2 processors are a very successful line of processors. They are based on the Core microarchitecture which offers a tremendous improvement in performance and power efficiency. There are currently over 30 different processor models based on three main core designs. They are split into several performance grades :

  • Core 2 Extreme (QX Series) - High-end quad-core Core 2 processor with unlocked multipliers
  • Core 2 Extreme (X Series) - High-end dual-core Core 2 processor with unlocked multipliers
  • Core 2 Quad (Q Series) - Mainstream quad-core Core 2 processor
  • Core 2 Duo (E Series) - Mainstream dual-core Core 2 processor
  • Pentium Dual-Core (E2000 Series) - Value-segment dual-core Core 2 processor
  • Celeron Dual-Core (E1000 Series) - Budget-segment dual-core Core 2 processor

Unlike the AMD Phenom quad-core processors which are built on a single die, Intel still build their Core 2 quad-core processors as multi-chip packages - essentially two dual-core dies combined into a single package. Even their new 45 nm Core 2 processors are built this way.

This has led AMD to claim that they are not "true quad-core" processors, and therefore inferior to AMD's monolithic quad-core design. However, this is really a minor distinction. The Intel Core 2 quad-core processors have four processing cores and that qualifies them as quad-core processors, whether they are built as two dies or a single die.

In this article, we compare the performance of 23 Intel Core 2 processors in five benchmarks - two game-based benchmarks and three application benchmarks. We hope to add on more and more results as we get hold of additional Core 2 processors over time. Let's take a look at the Core 2 processors we have rounded up for this comparison.
